[0002] In the construction and renovation industries, mortar mixing tools are used in equipment with an on-off valve at the mortar discharge port. Previously, ball valves and gate valves were used, but both had significant drawbacks. For example, due to the presence of fine sand and gravel crystals in the residual slurry tank, ball valves often jammed the main valve when opened, damaging the valve core and rendering it unusable. Gate valves require rotating the valve to open and close, which not only wastes time but also creates the risk of splashing residual slurry while waiting, reducing work efficiency. Currently, most valves in the industry are of these types, which cannot meet production needs and pose certain safety risks. Utility Model Content

[0020] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0021] As shown in the figure, the utility model is a valve device for slurry unloading, including a fixed valve base, a valve self-weight pressure plate 3, and a switch pressure rod 4. The fixed valve base includes a unloading chamber 1 and two positioning plates 2. The unloading chamber 1 is a square drum rack with front and rear ends connected. The two positioning plates 2 are respectively fixed on the left and right sides of the unloading chamber 1. The positioning plate 2 is provided with a groove 5, and the position of the groove 5 is set in front of the unloading chamber 1. The valve self-weight pressure plate 3 is rotatably connected to the unloading chamber 1, and the switch pressure rod 4 is rotatably set on the outside of the positioning plate groove 5. The switch pressure rod 4 is provided with a locking bolt 6.

[0022] The utility model discloses a valve device for residual slurry discharge, wherein the rear end of the fixed valve base is welded to the discharge port of the tank body. When closed, the valve self-weight pressure plate 3 covers the front end of the discharge chamber 1, the switch pressure rod 4 falls and is stuck in two grooves 5, and the locking bolt 6 supports the front of the valve self-weight pressure plate 3. When it is needed to be opened, the switch pressure rod 4 is opened, and the valve self-weight pressure plate 3 is automatically pushed open under the self-weight of the residual slurry, the valve automatically opens, and the residual slurry flows out according to self-weight. After the residual slurry in the barrel is discharged, the switch pressure rod valve is closed again, and the valve is recycled. The new valve described in the utility model eliminates the problems of the original valve such as clogging, spraying, loss of time, loss of life, and safety hazards, increases the discharge speed, and improves work efficiency.

[0023] The switch pressure rod 4 of the present invention is a long steel plate, and the groove 5 is a square groove. The width of the groove 5 is slightly larger than the thickness of the switch pressure rod 4. When the switch pressure rod 4 falls and is stuck in the groove 5, it will not rebound upward. In order to allow the switch pressure rod 4 to fall into the groove 5 more accurately, the present invention is provided with a guiding inclined surface 12 above the groove 5 to ensure that the position of the switch pressure rod 4 falling is accurate.

[0024] The valve deadweight pressure plate 3 is connected to the discharge chamber 1 through two rotating positioning pin shafts 7, and the switch pressure rod 4 is connected to the positioning plate 2 through the rotating positioning pin shaft 8.

[0025] The utility model adds a reinforcement plate 10 on the front side of the valve self-weight pressure plate 3, and the position of the reinforcement plate corresponds to the position of the locking bolt 6. When closed, the switch pressure rod 4 falls into the two grooves 5, and the locking bolt 6 supports the reinforcement plate 10, ensuring that the valve self-weight pressure plate 3 is not deformed and extending its service life.

[0026] The utility model provides a sealing gasket 9 on the contact surface between the back side of the valve deadweight pressure plate 3 and the discharge chamber 1 to ensure that no leakage occurs.

[0027] In addition, an inward bend 11 is provided above the valve self-weight pressure plate 3, which plays the role of initial positioning when closing and can also prevent dirt from falling between the contact surface of the valve self-weight pressure plate 3 and the discharge chamber 1.
